The Easy Road, and What is Sustainablity?


We have been blessed to take the easy road. We have the means to buy a bus ticket, to get on a plane and fly 3,000 miles down to Mexico. We are able to bring our surfboards, an extra bag full of books, presents, art supplies, special favorite food items and have our personal backpacks stuffed to the brim with lap-tops, cameras and other random gear.

Mexico City- Can it ever be sustainable?

Arriving in Hualtulco’s picturesque palm lined airport we are pleasantly surprised to be greeted by our friend Pepe who has come to escort us back to his home where our Truck and our home on the road, Ellie the Dodge has been awaiting us.

Why are we here again? To share ideas about sustainability? How much carbon have we created to make this journey? How is it we are giving talks about environmental awareness yet we ourselves are sucking up diesel fuel to power our way across borders?

It would be very easy to go on and on about the details of our daily lives that conflict with the mottos of being sustainable. In the end only nature is truly sustainable. We must design systems that mimic nature, regenerating resources rather than depleting them. So, we continue on…

The bottom line is many of us take the easy road because we can. We use what we have, and maybe that is the best we can do for now. We talked about bailing everything, just riding bikes or kayaking down the coast (hah, talk about new ideas!).

The justification for driving is that we are carrying tools and supplies to do projects, and hope to introduce novel ideas that may improve lives and the environment, thereby offsetting our impacts. Also, reality is we knew we wouldn’t be able to cover as much territory and be as equipped with any other method of transportation.

Once again, there are many ways to do things, there are many ways to live. We are blessed to have choices.

We found that we are not the only ones who chose the easy road. We were disappointed but not surprised to find that the composting toilet we built for Pepe had not been used. He has three other toilets for his 10 cabaƱas and it obviously wasn’t a necessity for him.

But after a week here we were able to talk him into getting it going again and helped him construct a privacy structure for it. It will serve as an extra toilet for his many customers from all parts of the globe.

The "Nature Toilet"

We checked out another property in town that is owned by a man from New Zealand. The only toilet they had on the land was a composting toilet, which they have been using for the last 5 years. They add lime powder (calcareous, or cal) and have not had to empty it yet, and it didn’t smell.

The Slow Sand Water Filter we constructed before we left town last October is still up and running, getting a lot of use from Pepe. Our recent water quality tests turned out good and we have been drinking from it for over a week, with no ill effects.

Tastes Great!

Loren gave a talk and showed a slideshow on Permaculture to an interested group of some traveling Irish and Aussie surfers. They were builders and educators, and hoped to learn more about Permaculture down the road.

Passionate about Permaculture

The Water Bottle Re-fill program has been working as well, and everyone seems to be enjoying the benefits of less plastic being used. The customers are happy to pay less for water, and the business owners happy to earn more money from the repeated sales.


All the while we have been enjoying some fun surf sessions. We were greeted by the familiar transition of coming from a cold climate with white skin, to the scorching blast of the tropical sun that singed our pasty flesh. Those midday surfs will do it! Mornings and evenings are the best working hours- you’re a bit safer from heat stroke.

Stay Tuned! We will be heading further south to Guatemala, El Salvador, and Nicaragua- in search of good work and good waves!

Relating, Creating, and Integrating!

A lot has happened in these last 2 weeks. On a global scale, it appears that there have been huge changes. For a tiny pueblito on the Pacific Coast of Mexico, watching the rest of the world’s frantic struggle over the economy and politics seems like just another dramatic soap opera on the talking box.

Still, small rural towns like these have their share of drama. Everywhere there is human culture there is almost always the common theme of the “struggle for power”.

To deal with this recurring dilemma of “who’s right, who’s wrong”, Barra de La Cruz has created a democracy of the people. As an indigenous town they are left mostly alone, free from most government financial support. This means a small health clinic and no federales.

The community makes all the rules; and if you don’t like them you can leave. If you break the rules, the “banda” may come to escort you out of town with sticks and machetes by their sides. Unruly people are banned from town. They recently constructed a new gate on the road into town, which is locked promptly at 9 p.m. and doesn’t open again until 5 or 6 a.m. If you’re in you’re in; if you’re out, you’re out.

A President and a Vice President are appointed each year, then the positions rotate to another member of the town. Each person in the community gets a turn at public service, be it being the police or serving food at the restaurant at the beach. Community meetings held bi-monthly, where up to 200 member of the town gather for a shouting match. We hear that it gets so heated that at least one person is hauled off to the town jail for being too rowdy. But for any significant changes to occur with in the town, the whole community must agree on it, which can often take months, even years.


The fact that we decided to park up at Pepe’s Cabanas, almost 2 months ago now was no coincidence. This was the spot we needed to be, and Pepe was the man we needed to meet!

It takes time to build relationships and to really get to know a place, especially in tight knight communities where one’s family heritage marks one’s standing, and it can takes generations to earn respect. Things are changing however, and old worlds are merging with the new.

The town of Barra is doing its best to protect its heritage, the sacredness of the land, and the interest of the people. Gringos, or “hueros” are not particularly popular here amongst some elderly locals. It is no surprise why, when most of what they see are fancy cars speeding through town, preoccupied with getting to the surf. There is little quality interaction between the two cultures.

Pepe is Vice President this year, and is a prominent figure in the community. He is well respected and educated. It has been a dream of his to make a way for foreigners to interact more within the community, sharing knowledge and experiences, and creating projects that benefit everyone. Perfect! He has been super stoked on our ideas, and gladly gave us the permission to proceed with them. His place was the first in town to implement the Water Bottle Refill Program, and the positive effects are already evident. Now the restaurant at the beach is doing the same.

Water Bottle Refill program in effect!

Our next sustainability project was to build a Slow Sand Filter for making the town water supply potable. The filter consists of a 50 gal (200 liter) plastic drum filled with rocks, gravel, charcoal, and sand. The sand acts much the same as a river-bank, and active bacteria and algae present in the sand remove up to 99% of disease causing pathogens like Giardia and Cryptosporidium cysts.

We heard that the local school does not have an art program. We have been really excited to do some art projects with more kids, so this was a great opportunity for us to work with them in further expressing their creative sides.


We had no idea what to expect coming to the school to “teach” an art class, and were a bit nervous. Our Spanish is decent to good, but kids always seem to catch every word that is not used correctly.


It was overwhelming to think these kids may never have played with colors. They were so incredibly excited when we pulled out the pads of blank paper and the packets of oil pastels. We had their full attention, all 20 of them!


The only thing I really wanted to show them was how to mix and make colors using the 3 primaries: yellow, red, and blue. With these three colors you can make the whole rainbow (arcoiris).


We did not want to give too much instruction, so as to not limit them with their own imaginations. I demonstrated how to draw a few flowers and how to make a star, and after that we set them loose! For a group of 9-10 year olds, their natural ability to make beautiful pictures was incredible. They really went for it!


After they were able to have some time experiencing drawing, we moved on to painting. Loren’s mom Linda donated us two large canvases and a bunch of acrylic paints and brushes. We laid them out in the middle of the school campus, and prayed that it would not rain. The kids attacked the canvases, covering them with mounds of color.

We spent three afternoons at the school with the kids. Their enthusiasm for trying new things was so refreshing. It was such a joy to watch them having so much fun. It was an amazing opportunity to connect with the community in such a simple way.

All the while the barra has been providing us something to ride. It has not been as good as it was, but still a great way to refresh and enjoy our Mother Ocean.



Thanks for sharing the journey!
